Hugh Jackman reveals the insane diet he used to get ripped for Wolverine movie role

Hugh Jackman's got it all: ruggedly handsome good looks, serious acting skills, and the boyish charm inherent in most Aussie men (read: Chris Hemsworth). The 49-year-old is known for taking on a number of very different roles in a variety of genres over the years, from his effort in action-horror flick Van Helsing to the epic historical romantic drama Australia, and even belting out a few tunes in the film adaptation of Les Miserables.

He's also well-known for having played Wolverine, first appearing as the mutant in Marvel's 2000 flick X-Men. Now, seventeen years later, Jackman is still portraying the character, most recently receiving acclaim for his stellar performance in the noteworthy Logan. Incredibly, he looks as fit as ever, his muscular arms and ripped six-pack certainly very easy to look at.

How does he do it? Well, we can tell you exactly the diet Jackman followed so you can look like Wolverine too. Minus the claws, of course.

The actor revealed that he follows something called the 8-Hour Diet, and it turns out it's quite popular with celebrities like Terry Crews and Nicole Kidman too. As you might've guessed, the diet works on any body type and is designed to switch on your fat-burning bits and ultimately help you look leaner.

Jackman revealed his tactic to Men's Fitness, who reported that it works by limiting your food intake to just eight hours over the course of the day. You fast for the rest of the 16 hours, meaning if you take your first bite at 10am, your last meal should be just before 6pm.

"I feel so much better on it," Jackman told the magazine. "And the great thing about the diet is, I sleep so much better."

The 8-Hour Diet is just another name for intermittent fasting, which reportedly has many beneficial side effects other than just keeping you leaner. By only eating during prescribed hours and holding off from food for the rest of the time, your body automatically starts burning fat, rather than muscle, for energy.

Limiting your food consumption to just eight hours also boosts your natural levels of the human growth hormone, meaning you'll build muscle more easily and get stronger as a result. Plus, the diet is also proven to help lower your risk of diabetes, cancer and even Alzheimer's.

It was especially effective for Jackman who needed to massively bulk and cut for the Wolverine role.

“I haven’t put on nearly the amount of fat I normally would,” he said. To gain muscle for the role, Jackman followed what was described as a "brutal, no-nonsense nutrition plan" that was personally prescribed to him by certified muscle-mountain Dwayne “The Rock” Johnson.

“He told me that if in a six-month period you want to put on 25 pounds of lean muscle and not fat, eat natural and eat 6,000 calories a day,” Jackman said. “There were times when I would literally eat with the mindset of working out. ‘One more mouthful, one more, come on, come on, you’ve got to finish this meal.’”

But most people don't eat quite so much when following the intermittent fasting plan. It's not exactly a new diet and is even considered by some as a "fad" that first started in 2013. Dietician/author David Zinczenko wrote a book introducing the 8-Hour Diet, and it had everyone hooked after he claimed it'll guarantee to help you lose major weight.

The best part is that it doesn't matter what you eat during the 8 hours, as long as it's balanced and protein-rich. It means Jackman could indulge in all his favourites, including sushi:
